Vaayu Hybrid Chiller - world's most "efficient" AC


Well-Known Member
YourStory featured a story on the product -

It does not mention from where they have taken the patent (US patent or Indian patent)

Whoever wrote the story does not even know the difference between refrigerator and refrigerant. @Mechanical guys on the forum, the working principle seems to be the same as any AC. Maybe the real procedure got lost in translation. But is this possible?
Nowhere in the article have they mentioned that some Indian university or lab has tested their product and backed up their claims.

From what I could understand, it looks like the usual air cooler, using a refrigeration cycle to chill the water. So I guess, as with other air coolers, this would work only if humidity is low.
